From eff8d43479e7704df65fae2a80eefa787213f502 Mon Sep 17 00:00:00 2001 From: skal Date: Mon, 9 Feb 2026 20:27:04 +0100 Subject: refactor: Reorganize tests into subsystem subdirectories Restructured test suite for better organization and targeted testing: **Structure:** - src/tests/audio/ - 15 audio system tests - src/tests/gpu/ - 12 GPU/shader tests - src/tests/3d/ - 6 3D rendering tests - src/tests/assets/ - 2 asset system tests - src/tests/util/ - 3 utility tests - src/tests/common/ - 3 shared test helpers - src/tests/scripts/ - 2 bash test scripts (moved conceptually, not physically) **CMake changes:** - Updated add_demo_test macro to accept LABEL parameter - Applied CTest labels to all 36 tests for subsystem filtering - Updated all test file paths in CMakeLists.txt - Fixed common helper paths (webgpu_test_fixture, etc.) - Added custom targets for subsystem testing: - run_audio_tests, run_gpu_tests, run_3d_tests - run_assets_tests, run_util_tests, run_all_tests **Include path updates:** - Fixed relative includes in GPU tests to reference ../common/ **Documentation:** - Updated doc/HOWTO.md with subsystem test commands - Updated doc/CONTRIBUTING.md with new test organization - Updated scripts/check_all.sh to reflect new structure **Verification:** - All 36 tests passing (100%) - ctest -L filters work correctly - make run__tests targets functional - scripts/check_all.sh passes Backward compatible: make test and ctest continue to work unchanged. handoff(Gemini): Test reorganization complete. 36/36 tests passing. --- CMakeLists.txt | 160
